like prostate exam kidney check up cuz unfortunately his doc only checks his ears lungs and heart?
It depends on if it is his first physical. Many checks can be done every 2 or 3 years. My last physical when I was 50 was just checking my vitals and doing routine blood work. My doctor did an EKG and digital exam the year before and these are not necessary every year.
My guess would be that he should get a complete physical at his age, top to bottom to make sure that everything is ok.
